6 Claims.

The principal object of my invention is to provide a highly etilcientdrying device-that may be-used successfully for economically dehydrating various materials and/or items, but isparticularly adapted for drying clothes, garments and like. V

A further object of this invention is to pro vide a dehydrator that does not soil, smudge or introduce an obnoxious odor to Lthe matter being dried.

A still further object of my invention is to provide a dehydrator that is economical in manufacture andl durable and economical inl use.

'Riese and other obiectswill bey apparent to thoseskilledintheart. i My invention consists in the construction, arrangement and combination of the .various parts ofthe device, whereby the objects contemplated are attained as hereinaftermore iully set forth,

pointed outinmy claims andfillustrated in the accompanying drawings, in which;

I and has lits top portion-cone' shaped. The numeral I designates a horizontal plate partition in the upper portion of the housing I5. The numeral I1 designates a plurality of .spaced apart vertical tubes in the housing I5 each having its uper end communicating with the area A of the housing above the plate I6 and its lower end communicating with the center inside top of the compartment chamber Il. VThe riumeral I8 designates a plurality of horizontal baille 'plates inside the housing' I5 and below the plate I6. These bafiie plates I8 are perforated toallow the passage of the tubes Il through them.

The ynumeral I9 designates an inverted cone shaped partition plate inside the housing I8 and directly above the housing I5. This plate I9 has its center open to communicate with an- .opening in the center top of th housing I5'as Fig. 1 is a side sectional view vof my device ready for use.

However, most of such de-A Y f vlees are objectionable in :het they are eesiiy to operate, tend to-soil or ila'i'n'age the materialoperated. Ihave being dried, end are not e'psiiy v -I .overcome such objections as will-be hereinafter appreciated;

Referring ie ine I have used ine :numeral Il to designate the Vhousing of my de- .vice open at its bottom and having doors I-I. 'Ihe numeral I2 a horizontal partition f in the lower part otthishousing for creating 'a closed chamber Il and a chamber I4 open'at' its bottom lits shown in Flg.- L Tlie numeral Il designates the heat and distributing" een no eeuuguy 'en the iop of ine plate partition l2.' This housing basa diamshown in Fig. `1. lThe numeral 20 designates a plurality of conduits inside the housing I0 having their lower ,ends communicating with the inside of the housing I5 at spacedapari; points directly below the plate I6 and their upper ends communicating with the inside bottom of the chamber I3 directly above the plate I9. The points where the conduits 20 communicate with the chamber I3 should be spaced apart and near 4the side of the'housing, I0. A damper valve 2l and damper handle' 22 may be mounted in each of the conduits 20. The numeral 23 designates an upwardly extending collar bearing on the center top oi the plate I9 and surrounding the openingin the center of that plate. The numeral 24 designates a downwardly extending collarbearing lon'the center inside top of the housing I0; This collar'surroundsan opening 25 inthe topof the housing III. The numeral 2B designates a vertical -pipe centrally located inside the housing Il having 'its lower. end iiifzaiwn ing in the collar 23 and its upper end bearing in the col1ar'24. The numeral 21 designates a plurality of horizontally radially extending rack rods on the pipe 26.' By this construction, the rods `2|and pipe 26 may be rotated kas a unit .and the pipe 26 will have its lo wer end communicating with the Ainside top' of .the housingil and its upper end communicating with the opening 25.

.The numeral 2l `designates a fan housingon top of ine housing-ip having iis'inlei port communicating'witli the opening 2l and the outlet port communicating with one end lof a pipe 29. The

numeral Il 'designates a rotatably mounted fan inside the fan housing and connected to the eieeiri motor ai. 'nie pipe n extends from' eter muchv less thanthe diameter of the housing l the fan housing and has its other end communieating with the inside of the housing Il at a pointbelow the bailies i8. 'I'he numeral 32 designates exhaust pipes communicating at various points with the inside top of the housing la. 'Ihe numeral 33 designates a gas or like burner. in the compartment I4 and directly below the pipes i1. The numeral 3l designates the fuel inlet pipe leading to the burner I3. Imposed in this pipe is a control valve and housing 35 shown in conventional form in Fig. 1 and controlled by a time switch or like mechanism shown in conventional form in Fig. l and designated by the numeral 3i. .The electric power wires are designated by the numerals 31 and l! which enter the switch II. .The numerals 3l and Il designate the motor 3| lead wires, one of which is electrically connected to the lead wire I1 and the other of which is electrically connected to the switch 3i.

To operate my device, it is merely necessary to set the device so that the burner will be treme outer area oi the compartment I3 will also be subjected to drylnt action.

Although I have described my device as particularly desirable for drying clothes and like, obviously, it is useful for drying various items, material and matter. By virtue of such air furnished the burner Il and by the control and direction of the heating air, my device is most economical in operation. From the foregoing it'will readily be seen that I have provided a highly desirable dehydrating device.

`Some changes may be made in the construction and arrangement of my improved dehydrator without departing from the real spirit and purpose of my inventio and it is my intention to cover by my claims any modified forms of structure or use of mechanical equivalents which may functioning and the fan 3l running.` The heat.

from the burner 33 will pass upwardly through the tubes I1 into the upper portion of the housing Ii. From this housing Il, the hot gaseswill bel pulled upwardly through the pipe 2l, then forced downwardly through the pipe 2| into the lower portion of the housing i5. 'Ihe hot gases entering the housing li will pass around the baille plates il in a sinuous path and around the pipes I1, then through the pipes 2l and into the compartment Il above the 'plate Il. The material to be dried is placed or supported inside the compartment I3. Supporting members for holding the material are secured pipe 2i. In the case of clothes or like, the same may be hung on radially extending rods 21. The hot gases pass upwardly in the compartment il through the matter to be dried and then out of the top of the housing III through the exhaust pipe 32. The movements of the air, heat and hot gases are shown byarrows in Fig. l. After the matter has been 'properly dehydrated, the doors il are opened and the dehydrated matter removed. The placement of the matter to be dried on the rods 21 and the ermoval of the same is facilitated by the possible manual rotation of the pipe 26 and supporting member 21. Obviusly. material may be hung on the rods 21 ad, jacent the doors il and Vthen rotated to positions :at the rear oi the compartment I3. The com- :plete movement of the air, heat and hot gases is f actuated by the fan 3l and the speed of movement of the same relative to the heat of the oil fburner 33 is such'that the material being dried would not be burnt or damaged even though the same comes in direct contact with the plate I l or pipe 2i. One of the chief features of this device is that the burner 33 has its bottom and sidesl in direct communication with the outside atmosphere. By virtue of rising heat and the action` of the ian Il, a maximum amount of air will iiow around the burner 33, thereby preventing its smoking or fouling the air andhot gases passing through the device. Obviously, all of the toV the rotatable be reasonably included within their scope.
